The Wall Street Journal is reporting that Federal Prosecutors are investigating claims that Kenneth Thompson, attorney for hotel maid Nafissatou Diallo, offered to hinder the prosecution’s efforts in their sexual assault criminal proceedings in return for a pay-off from Dominique Strauss-Kahn.

It was also reported that prosecutors had requested that Thompson turn over any information about settlement negotiations.

If the report is true, this would create additional doubts about Diallo’s credibility. A court hearing is set for Tuesday where prosecutors are expected to announce whether or not they intend to move forward on the case.
